As a poor kid growing up in a Los Angeles ghetto, I had dreams of going to college and becoming a teacher—a seemingly impossible desire considering our financial condition. Mama, who had her share of dreams, was always more of a realist when it came to the dreams of her children. She wanted me to become a barber. "People will always have hair," she'd argue logically. "It keeps growing. They'll always need a good barber. You can't fail."
I was a stubborn kid and refused to relinquish my dream. I found a way to realize it. After five years of higher education, I became a teacher with the monumental salary of six thousand dollars a year. Mama was quick to point out that, figuring the price of haircuts, I'd have made a lot more than that and after much less preparation. Are mamas ever wrong？
I can't even imagine a world without those dreamers who have the feeling that things will be better tomorrow. With the feeling comes a sort of self-fulfilling prophecy and causes us to work actively to make things better.
I'm not suggesting that we all start living an illusion, but it's an interesting psychological finding that one hundred percent realists are often among the most depressed persons in our society. I'll take healthy illusion any day. If our dreams cause us to become active seekers and partakers of life, setting up the necessary contingencies for making things happen, then they can be positive forces which are conducive to happiness and growth.
We might learn a lesson from Snow White. She dreamed that someday her Prince would come. But in the meantime, in place of moping around, she had a good life with the Seven Dwarfs!

For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the US had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war.
Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone.
Today Mars looms as humanity's next great terra incognita. And with doubtful prospects for a short- term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is-clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science. which has long played a minor role in exploration, is at last destined to take a leading role？ The question naturally invites a couple of others: Are there experiments that only humans could do on Mars？ Could those experiments pro- vide insights profound enough to justify the expense of sending people across interplanetary space？
With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life, If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
According to the passage, the chief purpose of explorers in going to unknown places in the past was ______.
